Anyone repaired a Maplins XM21X PSU?

Its always a nice warm feeling, when something has been resurrected, even if it's only the wallet that's feeling happier….

Just run it off an RCD for safety.  I run my whole observatory from an RCD anyway.

When you look at the Nevada unit, for example, you have to ask where is the specification sheet for it and what UK/EU standard markings does it carry?

As you say, without opening it up yourself how do you know how well it is built? and the answer is that you can’t and therefore you have to look at where you are buying from, the data sheets provided and the national-international markings it carries. 

For something that is really quite critical, even though rather boring, I would only be looking at specialist suppliers with full accountability, such as RS or Farnell Element 14 and I would expect to see a full data sheet/product specification.

If your observatory is going to be housing something in the region of ~£10,000 - £15,000 worth of equipment all linked to a single £40 power supply, well, do you really feel that is worth the risk or maybe spend up-to four times that for something that is fully compliant with current standards and the higher level of protection that is implied by those standards?

As they say, “You pays your money and you takes your chances” (sic). 

 

Don't believe Mike at Nevada would sell rubbish, it will be compliant.

I have a 35amp Microset 13.8Volt amateur radio supply which inside is much like James supply and has worked ok for more than 15 years.
It has powered expensive VHF/UHF rigs plus a 200watt solid state amp with no problem.

My AP setup was powered from a garden train switch mode supply capable of 15amps at 13.8Volts, no problem.
Both supplies have protected outputs and have no hesitation in using them.

Once everything is connected up properly there'll be an RCD on the consumer unit.
